This Year Alone Ive Changed 8 Cooling Fans To Cupra R Leons And 10 To V5 And 18 Toledos U Have To Change Both Fans. Fault Is Easy To Find By Puting On Aircon And Fast Speed On Fans Come On Then Go Off Then Come On And So On Got Fault Early In The Year With A V5 Toledo Blowing The 40amp Strip Fuse On Top Of The Battery. And Seat Technical Was Responsible For The Diognosis. But I Have Changed About 20 Water Pumps On Different Seats Due To The Impeler Falling Off Normal Fault Ok Doing Normal Speeds But Temp Very High With Warning Light Flashing In The End When Booting The Car On A Run. Hope Thats Helpfull
